Gut Health & Nutrition

The relationship between lifestyle, diet, and immune system health is complex and multifaceted. Evolution has equipped some individuals with genetic advantages that make them less susceptible to illnesses, while others are more prone to infections due to genetic and environmental factors.

A balanced diet and lifestyle play crucial roles in maintaining a strong immune system. The Mediterranean diet, rich in anti-inflammatory foods, combined with regular exercise, is often recommended. However, it’s essential to balance physical activity with rest, as excessive exercise can lead to elevated cortisol levels  – which particularly affects older women and increased stress, which negatively impact immunity.

The importance of gut health cannot be overstated. The modern diet, with its reliance on processed foods low in natural fibre, has disrupted our gut microbiome. Consuming a variety of minimally processed plant-based foods is critical for maintaining a healthy digestive system. Emerging fields like psychoneuroimmunology are exploring how the central nervous system and immune system interact, further highlighting the need for stress management techniques such as meditation, yoga, and proper sleep hygiene. Factors like circadian rhythm disturbances and chronic sleep deprivation can compromise immune function, emphasising the necessity of a holistic approach to health that includes adequate rest, stress reduction, and balanced nutrition.
